丨1343676 九、發明說明： 【發明所屬之技術領域】 本發明係關於在CPU插座等外框内部具有晶格構造的平 面狀連接器。 【先前技術】 液晶性聚合物於熱可塑性樹脂中已知有尺寸精確度、防 震性、流動性優良，且成形時極少發生溢料的材料。以往， 多活用此類特徵，將液晶性聚合物採用作為各種電子零件 @的材料。丨 1343676 IX. Description of the Invention: The present invention relates to a planar connector having a lattice structure inside an outer frame such as a CPU socket. [Prior Art] The liquid crystalline polymer is known in the thermoplastic resin as a material which is excellent in dimensional accuracy, shock resistance, fluidity, and which rarely causes flashing during molding. In the past, many of these characteristics have been utilized, and liquid crystal polymers have been used as materials for various electronic parts.

尤其，隨著近年來的電子機器之高性能化，亦有所謂之 連接器的高耐熱化（以安裝技術提高生產性）、高密度化（多 芯化）、小型化之時代性的要求，已有活用上述液晶性聚合 物的特徵，並將經玻璃纖維強化的液晶性聚合物組成物採 用作為連接器（全調查 Engineering Plastics ’92-’93， 182〜194 頁，1992 年發行，JP-A9-20495卜 JP-A6-240115)。 於CPU插座所代表的外框内部具有晶格構造的平面狀連接 器中，上述高耐熱化、高密度化、小型化的傾向顯著，多 採用經玻璃纖維強化的液晶性聚合物組成物。 但是，即使為具有某程度良好流動性的玻璃纖維強化液 晶性聚合物組成物，於使用作為近年所要求之晶格部間距 間隔為 2mm以下、保持端子之晶格部的樹脂部分厚度為 0.5mm以下之非常薄身的平面狀連接器方面，性能仍不充 分。即，於此類晶格部之非常薄身的平面狀連接器中，若 欲對晶格部填充樹脂，則因流動性不夠充分而使填充壓力 6 326\專利說明書(補件)\94-07\94107779 1343676 變高，結果具有所得之平面狀連接器之彎曲變形量變多的 問題。 為解決此問題，雖考慮使用玻璃纖維添加量減少之流動 性良好的液晶性聚合物組成物，但此類組成物強度不足， 產生因安裝時的迴焊而變形的問題。 如此，目前狀況為仍未取得性能平衡優良的液晶性聚合 物製平面狀連接器。 【發明内容】In particular, with the high performance of electronic devices in recent years, there are also demands for high temperature resistance of the connector (improvement of productivity by mounting technology), high density (multi-core), and miniaturization. The liquid crystal polymer composition having the above-mentioned liquid crystal polymer has been used, and a glass fiber-reinforced liquid crystalline polymer composition has been used as a connector (Full Investigation Engineering Plastics '92-'93, 182-194, issued in 1992, JP- A9-20495, JP-A6-240115). In the planar connector having a lattice structure in the outer frame of the CPU socket, the above-mentioned high heat resistance, high density, and miniaturization tend to be remarkable, and a glass fiber-reinforced liquid crystal polymer composition is often used. However, even in the case of a glass fiber-reinforced liquid crystal polymer composition having a certain degree of fluidity, the resin portion having a lattice spacing of 2 mm or less as required in recent years and holding the lattice portion of the terminal is 0.5 mm. In terms of the very thin planar connectors below, performance is still insufficient. In other words, in a very thin planar connector of such a lattice portion, if the crystal lattice portion is to be filled with a resin, the filling pressure is insufficient due to insufficient fluidity. 6 326\Patent Specification (Supplement)\94- 07\94107779 1343676 The height becomes high, and as a result, there is a problem that the amount of bending deformation of the obtained planar connector increases. In order to solve this problem, a liquid crystal polymer composition having a good fluidity with a reduced glass fiber addition is considered, but such a composition is insufficient in strength and causes a problem of deformation due to reflow at the time of mounting. As described above, the current state of the art is a liquid crystal polymer planar connector which is not yet excellent in performance balance. [Summary of the Invention]

如上所述，關於具有晶格構造之平面狀連接器中所用的 液晶性聚合物組成物雖已進行各式各樣的檢討，但尤其關 於晶格部之間距間隔為2 m m以下、晶格部之厚度為0 . 5 m m 以下之非常薄身的平面狀連接器，並未存在成形性、平面 度、f曲變形、耐熱性等性能均優良的材料。 本發明者等人有鑑於上述問題點，為了提供性能平衡優 良之液晶性聚合物製平面狀連接器而進行深入研究 '檢 討，發現於纖維強化液晶性聚合物組成物中，在所配合之 纖維狀填充劑的重量平均長度與配合量具有一定的關係之 情況，可取得成形性良好、平面度、f曲變形、耐熱性等 性能均優良的平面狀連接器，遂完成本發明。 即，本發明為由於（A )液晶性聚合物中配合有（B )纖維狀 填充劑之（C )複合樹脂組成物（但，配合之（B )纖維狀填充劑 的配合量與重量平均長度的關係滿足以下區域（D )的規定 内）所形成，且於外框的内部具有晶格構造的平面狀連接 器。 326\專利說明書(補件)\94-07\94107779 1343676 係 較 黏 或 香 為As described above, various liquid crystal polymer compositions used in a planar connector having a lattice structure have been subjected to various reviews, but in particular, the lattice spacing is 2 mm or less and the lattice portion is A very thin planar connector having a thickness of 0.5 mm or less does not have any excellent properties such as formability, flatness, f-bend deformation, and heat resistance. In view of the above problems, the inventors of the present invention have conducted intensive studies to provide a liquid crystal polymer planar connector having excellent performance balance, and found that in the fiber-reinforced liquid crystalline polymer composition, the fiber is blended. In the case where the weight average length of the filler has a certain relationship with the blending amount, a planar connector excellent in moldability, flatness, f-bend deformation, heat resistance, and the like can be obtained, and the present invention has been completed. That is, the present invention is a (C) composite resin composition in which (B) a fibrous filler is blended in (A) a liquid crystalline polymer (however, the blending amount and weight average length of the (B) fibrous filler are blended. The relationship is satisfied by the following region (D), and has a planar connector having a lattice structure inside the outer frame. 326\Patent specification (supplement)\94-07\94107779 1343676 is more sticky or fragrant

It is particularly effective in the case of a very thin planar connector having a resin portion thickness of 0.5 mm or less and a height of the entire product of 5.0 mm or less. If such a planar connector is described in further detail, the connector shown in Fig. 2 formed in the embodiment has a number of holes of several hundred pins (p i η ) in a product of about 40 mm x 40 mm x 1 mm.

The forming method for obtaining a connector having such excellent flatness is not limited, and an economical injection molding method is preferably used. In order to obtain a connector having such excellent flatness, it is important to use the above-mentioned liquid crystalline polymer composition, and it is preferable to select a molding condition free of residual force. In order to reduce the filling pressure and reduce the residual internal stress of the device, the temperature of the cylinder of the molding machine is preferably higher than the melting point of the liquid crystal T°C. If the cylinder temperature is too high, the grease is decomposed and the cylinder nozzle is stuck. For problems such as silk, the steam is T ° C ~ (T + 3 0 ) ° C, preferably T ° C ~ (T + 15 ° ° C). Further, the mold is preferably 70 to 1 0 0 °C. If the mold temperature is low, the flow of the filled resin group is poor, which is poor, and if the mold temperature is too high, problems occur, which is less preferable. Regarding the injection speed, it is preferably 1 500 m / s e c. When the injection speed is low, there is a molded article in which only the unfilled molded article is obtained or the molded article which is completely filled is a high filling pressure and a residual force is large, and a connector having only a flatness difference can be obtained.
